0.2.0 EZ2810 Special Features
Preset Weight
The EZ2810 indicator provides simple to use and very useful Preset Weight feature. Using the numeric keypad the operator can enter the desired weight of product that the operator wants to load or unload. Once loading or unloading begins the EZ2810 will count down to 0 (zero). As the weight approaches 0 the audio and visual alarms will begin to pulse with the frequency of the pulses increasing the closer the preset weight gets to 0. At 0 the alarm light and buzzer will sound continuously.
See section 2.2.0 for details.
Rotation Counter / Timer
The Rotation Counter / Timer provides the useful benefit of monitoring mix revolutions or mix time and a warning light, buzzer, or external signal will indicate when the desired mix revolutions or time has been achieved. For this the EZ2810 uses an optional Rotation Counter Sensor (See Option Equipment Section: 7.5.0) which is fitted to the drive line of the feed mixer. See section 2.9.2 for details.
Maintenance Message
The Maintenance Message is available with the Machine Hour Meter function noted above and provides the ability for the equipment manufacturer or equipment owner to utilize the EZ2810 to display a specific Service or Maintenance message after a predetermined period of operation similar to a Change Oil message in an automobile.
See section 2.9.5 for details.
Machine Hour Meter
The EZ2810 when fitted with the Rotation Counter Sensor can be configured to record hours of operation. The Machine Hour Meter can provide valuable information to aid the user in determining when maintenance and upkeep is required.
See section 2.9.6 for details.

0.3.0 Accuracy Statement
READ THIS SECTION BEFORE USING THE SCALE SYSTEM Digi-Star Scale Systems are designed and manufactured to provide the greatest accuracy possible. However proper installation and use are required in order to obtain the highest level of accuracy. When using the scale system the following must be considered in order to realize the best possible performance and accuracy.
Load cells must be installed with the proper orientation. Most Digi-Star load cells have a label indicating either the “TOP” or bending direction of the load cell. Inspect load cells to determine if the load cells are installed correctly. Incorrect installation of load cells will result in inaccurate measurement.
Load cells should not be subjected to any strains or loads other than the weight of the load. Stress or strain caused by misalignment or other factors when accurate weight readings are desired will negatively affect the accuracy.
The weighing unit should be stationary with minimum movement, and on a level surface, to insure that weight readings are as accurate as possible.
o The effect of movement on accuracy depends on the speed and roughness of the ground and application. Rougher terrain and faster and/or greater movement increases the degradation of accuracy.
o A level surface is defined as being less than a 5” (13cm) change in rise over 10’ (3.0m) of run. As the slope of the terrain increases, degradation of accuracy will also increase.

6.1.0 Indicator Mounting
For most applications the equipment manufacturer provides the necessary mounting system and hardware, and mounts the Indicator for the End User. Digi-Star provides a number of mounting options that allow the end user to customize the location and placement of the Indicator. The following section provides a list of the optional mounts. In all cases the Digi-Star Indicator must be securely mounted to the equipment. Loose, or unsupported, Indicators can be damaged.

6.2.0 Cable Connections
For accurate and reliable operation care should be taken when routing and connecting cables to the Digi-Star Indicator.
Cables should be secured and protected from damage and abrasion.
Long cables should not “hang” by the cable connector at the Indicator but should be secured to a structure close to the Indicator leaving a short “tail” to connect to the Indicator
Special Considerations for Power (+) and Ground (-):
The Digi-Star Indicator is designed to operate at a continuous voltage ranging from 10.5 to 16.0 volts.
Intermittent voltage drops to as low as 9.0 volts, such as when starting an engine, will be tolerated. Continuous low voltage will result in a Low Voltage warning on the display or the Indicator will power off.
Voltage spike above 16 volts will damage the Indicator. Never weld or charge the battery on the equipment that the Indicator is mounted to without disconnecting the Indicator power cord. Never operate an Indicator on equipment with an engine charging circuit when the battery has been removed.
Digi-Star recommends that the red power (+) and black ground (-) are connected as follows:
Power (+) can be either switched or keyed On & Off, or un-switched and always On.
Power (+) and Ground (-) should come from a dedicated auxiliary power source when provided. When auxiliary power sources are not provided power should come from the main power distribution system.
Fuse or circuit protection of at least 5 amps, but no more than 10 amps, should be provided. Although the Indicator is protected internally by an internal fuse a fuse or circuit protection is required to protect the power cable and equipment.
Ground (-) connection should be made to a main ground (the battery ground (-) is often connected to this location). Do not use the chassis or frame of the equipment as a ground.

SECTION 8 — Troubleshooting
8.1.0 Flow Chart
FLOW CHART
Check all J-Box and Load Cell cables for cuts or pinched/flat
spots.
START
YES NO Does the indicator come on?
Is the reading on the Indicator stable?
YES
Put your weight on each load cell. Does the indicator
respond to your weight?
NO
If your display is unstable, or flashes “±RANGE” disconnect the j-box cord from Indicator.
Is display still unstable?
NO
YES
YES
Your Indicator is probably defective. Try another
Indicator to verify. Note: Be aware of electrical interference that might
affect Indicator, such as mobile phones, CB radios, radio towers, electrical motors, etc. Make sure Load Cell
cables are not attached to hydraulic lines or
reservoir.
Are the readings all positive? If not
Load Cell is upside down.
Poor Connection: Take them apart and clean connections. (Rust or paint should be wire
brushed.) Then reconnect and tighten securely.
Bad Battery: Replace battery (weak battery may test good if tested with no load on battery) Bad Power Cord: Make sure red wire is connected to (+)
positive side and black wire is connected to (-) negative side.
When using a multimeter to check for voltage, measure
between pin 1 (pos) and pin 2 (neg). Meter should read
between 10.5 and 14.5 volts DC if using a tractor power
cord, black wire is positive and white wire is negative.
Bad Indicator: Try another Indicator. (Even a different
model or set-up should come on.)
Does the scale weigh you approx. the same over all Load Cells? (Weight will
not be accurate)
YES
NO
Remove the cover from your J-Box
Is there moisture inside the box? YES
Dry out your J-Box (use a hairdryer). Check cable
strain reliefs for tightness. Cables have drip loops. Is
lid gasket damaged?
NO
Look for loose connections. Watch your Indicator display while moving the wires and pressing on the circuit board inside the J-Box. You will see if there is a loose connection
or bad solder joint.
Your Indicator is probably not set-up and calibrated correctly. Check the decal on the bottom of Indicator. It shows what type of Load Cells the
Indicator was calibrated to. By pressing the on key while the
Indicator is already on, you will get the Indicator’s “Set-up” and “Cal”
numbers. See if they compare to the set-up and calibration numbers on the Indicator. Contact Dealer for
further information.
Fix or replace the J-Box Did the J-Box have a bad connection or loose wire?
YES
NO
D4008 - EN EZ2810 Operators Manual 50
FLOW CHART
Continued
1. Disconnect all the Load Cell wires from the terminal blocks
inside the J-Box (leave the Indicator on while connecting and disconnecting the wires, it will not damage Load Cells or Indicator if wires are shorted
during this step). Is reading on Indicator stable?
2. Zero balance the Indicator. (Press “NET/GROSS” then
“ZERO”). Indicator should display “0”.
YES
Replace J-Box (be aware of electrical
interference that might affect your scale such as: mobile phones, CB radios, radio
towers, electric motors, etc.).
NO
Note: Hook up the Load Cells to the J-Box one at a time (only one Load Cell connected at a time). This will get a reading for each Load Cell. While
performing this test, watch for any other
symptoms such as erratic/unstable display. Indicator flashing “±RANGE”, negative reading, etc. If the Indicator reading should ever appear
abnormal with any Load Cell connected then it is probably bad.
4. Record the Indicator reading with the Load Cell connected.
3. Connect one Load Cell back into one of the terminals in the J-Box. (The reading you get for
each Load Cell is dependent on the size and type of each Load Cell and how much weight is over
each Load Cell. In general, the number should be positive and stable.)
5. Stand or hang your weight over the connected Load Cell. Record how much the weight
increased with your weight over the Load Cell. (A scale with only one Load Cell will weigh heavy.)
Note: If the scale responded to your weight, that’s verification on the J-Box is OK. If the
scale did not respond, either that Load Cell is bad or the J-Box is bad. Try the other Load
Cells. If the Indicator still shows no response, the J-Box is bad. (Replace J-Box)
6. Disconnect the first Load Cell and reconnect a second one. Record the Indicator reading.
Stand or hang your weight over the connected Load Cell. Record how much the weight
increased.
7. Repeat step 6 for the remaining Load Cells. Remember to record your readings.
Do not expect the Load Cells to give the same reading. It is common for Load Cells to have
readings that vary by hundreds, even thousands. Especially when one is carrying more weight.
8. Bad Load Cells will have a reading that is either unstable, makes the indicator flash
“±RANGE” or is more than three times greater or less than the average of the others. Also the
readings of your weight over each Load Cell should be similar. (Probably 4 times your actual weight). Any differences could be an indication
of a bad Load Cell or a structural problem.
